What is a troded pentode???

Posted by Pär on April 18, 2000 at 06:25:45:
What is a trioded pentode (or beamie for that matter)?
Should the signal be connected on g1 or g2 (or both)?
Should g2 be connected directly to A or via a smallish value resistor?
Should g3 be connected to A or K?
There are many ways to do it, and which counts as 'Triode', 'Pseudo' or 'Fake'?
What are we comparing? There are possibilites from " I troded my old radio set and it sounds rubbish" to Williamson with 807/KT66 in triode mode (signal g1, g2 to A via resistor, and g3 to K as "default").
Some ways.... (Steve Bench)
